Earth distance calculator

Written in 2008 and rediscovered in 2012, this page calculates the geodesic between any two points using an accurate ellipsoidal model of the Earth using Vincenty’s formula and WGS84. Its code is accurate within 0.6mm. WGS84 is a theoretical ellipsoidal model and does not account for altitude but is significantly more accurate than spherical models.

These formats are recognized: -142.36, 36.5W, 73 38', 12 52' 25"
